How can I specify custom images for the GroupCaptionPlusMinus cell?

 

You can use the QueryCellStyleInfo() event to customize the images that appear in the GroupCaptionPlusMinus cell, when there are nested tables as shown in the following code snippet:

C#

private void GridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Web.UI.WebControls.Grid.Grouping.GridTableCellStyleInfoEventArgs e)

{

if(e.TableCellIdentity.TableCellType == GridTableCellType.GroupCaptionPlusMinusCell)

{

e.Style.CellType = "Image";//changing the cell type to image type

if(e.Style.Description == "+")

e.Style.ImageUrl = "myplusimage.gif";//specify location of plus image

else

e.Style.ImageUrl = "myminusimage.gif";//specify location of minus

}

}

VB

private void GridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As Syncfusion.Web.UI.WebControls.Grid.Grouping.GridTableCellStyleInfoEventArgs)

If e.TableCellIdentity.TableCellType = GridTableCellType.GroupCaptionPlusMinusCell Then

e.Style.CellType = "Image" 'changing the cell type to image type

If e.Style.Description = "+" Then

e.Style.ImageUrl = "plusimage.gif" 'specify location of plus image

Else

e.Style.ImageUrl = "minusimage.gif" 'specify location of minus image

End If

End If
